Engine oil
Use winter grade engine oil for winter operation!
In order to assure perfect cold starting it is import
to chose the viscosity (SAE-class) of the engine oil
according to the ambient temperature.
For winter operation below -10°C the oil change in-
tervals must be shortened.

Lubrication oil with a too high viscosity index caus-
es starting difficulties. The temperature when
starting the engine is therefore of highest impor-
tance when choosing the viscosity of engine oil for
winter operation.
Oil viscosity
Since lubrication oil changes its viscosity with the
temperature, the ambient temperature at the oper-
ating location of the engine is of utmost impor-
tance when choosing the viscosity class (SAE-
class) (see diagram).
Occasional falling short of the temperature limit
(e.g. use of SAE 15W/40 down to -15°C) may ef-
fect the cold starting ability of the engine, but will
not cause any engine damage.
Temperature related lubrication oil changes can
be avoided by using multi-purpose oils. The follow-
